Internal Computer Hardware
Motherboard
A motherboard provides the electrical connections by which the other components of the system communicate.
Central Processing Unit
The Central Processing Unit (CPU; sometimes just called processor) is a machine that can execute computer programs. It is sometimes referred to as the brain of the computer.
Random Access Memory
Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down.
Firmware
Firmware is loaded from the Read only memory (ROM) run from the Basic Input-Output System (BIOS). It is a computer program that is embedded in a hardware device, for example a microcontroller.
Power Supply
The power supply converts about 100-120 volts of AC power to low-voltage DC power for the internal components to use.
Removable Media
DVD
DVD-ROM has data which can only be read and not written. DVD-R and DVD+R can be written once and then function as a DVD-ROM. DVD-RAM, DVD-RW, or DVD+RW hold data that can be erased and re-written multiple times.
Blu-Ray
Blu-ray is a newer optical disc storage media format. Its main uses are high-definition video and data storage. The disc has the same dimensions as a CD or DVD. The term “Blu-ray” comes from the blue laser used to read and write to the disc.
CD
CDs are the most common type of removable media. They are inexpensive but also have short life-span.
There are two types of devices in a computer that use CDs: CD-ROM drive and a CD writer.
Floppy Disk
A floppy disk is a type of data storage that is composed of a disk of thin, flexible(“floppy”) magnetic storage medium encased in a square or rectangular plastic shell.
Internal Storage
Hard Disk Drive
A hard disk drive (HDD) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
Solid State Drive
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive, thus easily replacing it in any application.
Disk Array Controller
It almost always implements hardware RAID. RAID (Redundant Array of Independent Drives) is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, and/or larger data volume sizes.
